FLINT, MI - Officials say a recent city hall break-in occurred in an office containing documents related to the city's water system.

Flint police previously reported a break-in at City Hall, 1101 S. Saginaw St. over the holiday break, but information released Monday, Jan. 11, confirmed the break-in happened at a vacant executive office in the mayor's suite that contained documents related to the city's water system.

"The office that was broken into is where some water files are kept," Flint Mayor Karen Weaver said. "However, at this point it's hard to tell if any files were taken. The only thing we know for sure was stolen is a TV."

Flint Police Chief James Tolbert said investigators were working to discover if any documents connected to the city's water system were taken.

The break-in was discovered Dec. 28 by an employee when they returned from work following the holiday break. No other offices were disturbed.

"The video doesn't show anything," Tolbert said. "Officers are now doing a security survey."

The U.S. Attorney's Office confirmed Jan. 5 that it was working with the Environmental Protection Agency to investigate issues surrounding the city's water crisis.

Elevated blood lead levels have been detected in some of the city's youngest residents after the decision to use the Flint River as the city's water source. The decision was made while the city was run by four separate emergency managers appointed by Gov. Rick Snyder.

In October, the state Department of Environmental Quality acknowledged that it had failed to require the city to treat Flint River water to make it less corrosive.

Corrosive water also caused lead to leach from pipes and fixtures, and the number of children with elevated blood lead levels in the city more than doubled while the river was in use, according to a Flint pediatrician's study released in September.
